LAMP-BURNER.

Application filed April 4, 1910. Serial No. 553,221.

To all whom it may concern:

Be it known that I, THOMAS SHEARER, a citizen of the United States, residing at T0- ledo, in the county of Lucas and State of Ohio, have invented a new and useful Lamp- Burner, of which the following is a specification.

This invention has for its object to provide in a lamp burner a novel and improved deflecting device for shutting off end draft from the aperture in the dome of the burner through which the flame extends, to supply the projecting end of the wick with an increased amount of oxygen, thereby increasing the size and brilliancy of the flame.

It is also the object of the invention to provide a device of the kind stated which can be readily applied to any ordinary burner using a flat wick, without altering or modifying the structure of the burner, and without cutting or otherwise defacing the same.

\Yith these objects in view, the invention consists in a novel construction and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawing, forming a part of this specification, in which drawing,

Figure 1 is a perspective view of the device removed from the burner. Fig. 2 is a vertical section of a lamp burner showing the device applied thereto. Fig. 3 is a similar section taken on the line 3--3 of Fig. 2.

In the drawing the invention is shown applied to an ordinary lamp burner, the base of which is indicated at 5, and the dome at 6. I11 the upper portion of the dome is an aperture or slit 7 through which the flame from the burning wick passes. The wick tube 8 is arranged within the dome and the base of the burner in the usual manner, said tube being flat to receive a flat wick 9. The usual means are provided for raising and lowering the wick. In the base is a foraminous horizontal partition 10 through which the wick tube eX- tends. The parts thus far descrbed constitute an ordinary form of lamp burner, in common use and as the same forms no part of the present invention, a further descrip tion thereof is thought unnecessary.

The deflecting device shown in Fig. 2 is mounted in the dome 6 so as to surround the end of the wick tube extending thereinto, and in spaced relation with respect to said tube. The device comprises end walls Specification of Letters Patent.

11, and side walls 12. The end walls are perpendicular and are located opposite the ends of the wick tube. The side walls 12 are inclined upwardly, and inwardly, and are located opposite the sides of the wick tube. On the top edge of the end walls are fingers 13 for securing the device in the dome, said fingers being bent over the ends of the slit 7 as clearly shown in Fig. 1. No other fastening means are required, and the device is therefore attached to the dome without cutting or otherwise defacing the same. The upper end of the deflector extend-s to the slit 7, and its lower end is in contact with the partition 10.

The manner in which the deflector is secured to the dome enables it to be applied to any ordinary lamp burner of the kind stated, no alterations or modifications in the structure thereof being necessary. It may be formed of a single piece of any suitable sheet metal which is cut or stamped out to the desired shape, and then bent to the form shown in Fig. 3, the ends of the sheet overlapping. The device is therefore simple, and can be easily and cheaply constructed.

hen the deflector is in position within the burner dome as shown in Figs. 2 and 3, all end draft from the slit 7 is shut off, and an increased supply of oxygen to the projecting portion of the wick is obtained, thereby increasing the size of the flame, as well as the brilliancy thereof, and producing a steady burning clear white light of great illuminating power. The walls 11 and 12 surrounding the wick tube produce an updraft, the air entering the dome through the foraminous partition 10, and passing upwardly through the space inclosed by said walls. The inclined Walls 12 deflect the air passing between the dome and said walls into the flame from the sides thereof. The end walls 11, adjacent to the fingers 13, are bent outwardly to fit the wall of the dome at this point so as to close up the space between the end walls and the dome, and thus prevent all end draft on the flame.

The device can be applied to any flat wick lamp or lantern burner, as well as to heating or cooking oil stoves employing a straight or flat wick.

Inasmuch as the device can be applied to any lamp burner of the flat wick type, it may be manufactured and sold separate from the burner, and thus applied to an old burner.

\Vhat is claimed is:

The combination With a lamp burner comprising a base, a foraminous partition therein, a dome over the partition, said dome 5 having a slit, and a Wick tube extending through the partition into the dome; of an air deflector Within the dome, said deflector comprising side and end Walls surrounding the Wick tube in spaced relation therewith,

10 and the top of the end Walls having out- Ward bends engaging the Wall of the dome at the ends of the slit to close the space between the said Walls and the dome.

In testimony that I claim the foregoing as my own, I have hereto afliXed my signature 15 in the presence of two witnesses.

THOMAS SHEARER.
